Tensor perturbations in inflationary models as a probe of cosmology.

Abstract

In principle, the tensor metric (gravity-wave) perturbations that arise in inflationary models can, beyond probing the underlying inflationary model, provide information about the Universe: ionization history, presence of a cosmological constant, and epoch of matter-radiation equality. Because tensor perturbations give rise to anisotropy of the cosmic… (More)
